TO ALL WHOM IT MAY CONCERN:

De it known that I, EWING-W. TIBBELS, of Chester, in the county of Delaware, and State of Pennsyl vania, have invented a new and useful Improvement in Stump-Extractors; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying draws ings, making a. portion of this specification, in whi'ch- Figure l isa plan view of a stump-extractor made according to my invention.

Figures 2 and 3 are detached views of one portion of the same.

Similar letters of reference indicate corresponding parts in all the igures.

This invention consists n the combination of awheeled draught-axle, drag-bar, andlever w'ith an att-aching.- ehain and dog, whereby a stump may be wrenched around upon its vertical axis, and loosened and torn from the eartl1, with acomparatively moderate expenditure ot power, that power being exerted in a rotary direction around the stump, at the outer end of the lever. y f

To enable others to understand the construction and operation of my invention, .I will proceed to describe it with reference to the drawings.

A is an axle, furnished at its ends with suitable wheels, B, and having attached thereto the thills C, or any equivalent therefor. Pivoted at its forward endete the cent-re of th'e axle is a. strong bar, D, the real-most end of which is sutfered to drag upon the ground. APivoted at any suitable point to this drag-bar D is one end of a strong lever, E, the opposite end of whichnlay be made of cylindrical form, to receive a collar, a, having attached thereto a chain, F, to the free or outer end ot` which is secured a dog, Gr, formed with a sharp lip or edge, b.

In order to use the machine, the lip or edge b, of the dog G, is rstdriven into the side of the stump, I, indicated in iig. 1, and the chain F is coiled around the stump, in the manner shown inv such figure, and a horse or other draughtanimal being attached to the axle A, between the thills C, the axle is drawn around-the stump in a rotary direction, so as to tighten the chain upon the stump, and this draught upon tbe chain being con- `tinued, the stump is wrenchcd and twistdaround its vertical axis, and is thus eifectually loosened and torn from the earth, the power required-inextracting the stump in this manner beingl materially less than in those cases where the stump is forced over or tilted laterally, or withdrawn by a vertical movement. What I claim as my4 invention, and desire to secure by Letters Patent, is-

The combination ofthe wheeled draught-axle A, the drag-bar D, and the` lever'E, with the chain and the dog attached thereto, for operation, substantially -as and for the' purpose speced.
